2021 April 20 Sun - solar surface in white-light, with AR12815, AR12816, AR12817 and possible AR12818 and possible AR12819

AR12814 has turned to the backside.
AR12815 has no sunspot. A patch of faculae is visible.
AR12816 is very active, with 4 sunspots that come with penumbrae.
AR12817 is very active, with at least 8 sunspots. However, I cannot take images of this group due to clouds.
To the east of AR12817 is a small AR where 1 sunspot is visible. This may become AR12818.
On the SE limb, an AR shows up with bright faculae and a lone sunspot. This will be AR12819.
sunspot count: group=4, sunspot=14, R=54
